Cooling solutions in metal slag recovery

Refrigeration in the metal slag recovery industry

Adapting a cooling tower design in a light metal treatment industry in Vizcaya, which works principally in valuation of metallic residues.


Design, manufacture and installation of the slag circuit cooling system.

Chemicals substances dissolved in water cause precipitation of salts, as well as the amount of suspended matter, are the main challenge to get an effective cooling system over time.


The cooling tower must have materials especially resistant to chemicals and erosion. On the other hand, the water distribution system and fill packs should especially favor the circulation of water loaded with suspended matter, avoiding clog the cooling circuit. Finally, it should allow easy access to internal components for cleaning and maintenance.
